TRANSMISSION-HAN GER.

Specification ofLetters Patent.

Patented Dec. 31, 1.918.

Application filed April I, 1918. Serial No. 228.868

To all whom it may concern.

' Be it known that I, HAupLn M. Bann- BUnY, citizen of the United States of America, and resident of Cambridge. in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Transmission-Hangers, of which the following is a specification.

This invention relates to a supporting device and more particularly to a device for supporting the crank-ease or change-speed gearing or other portion of the transmission upon the chassis of an automobile.

Devices more or less similar to the present devic have been proposed heretofore. but so far as I am aware they have been unsatisfactory in that they have failed to sup port the transmission sufficiently tightly and have, therefore, permitted vibration and relative movement of the parts. This has resulted in chafing, under wear and breakage.

The principal objects of the present 1n vention are to provides device whichwill .be free from the aforesaid defects, which may be tightly secured to the transmission, which will not shake loose from the transm1ss1on in use, and which will minimize relative movement between the device and the parts 'colmectedthereto. Other objects of the invention will be apparent from the following description and the accompanying drawings in which'- Figure 1 is a top plan view of a transmission casing supported between chassis beams by means of two of my improved hangers;

Fig. 2 is a top plan view of one o'l my improved hangers'on an enlarged scale;

Fig. 3 is a side elevation oi the hanger viewed from the left of Fig. 4; and

Fig. 4 is an end elevation oi the hanger showing it attached to a chassis beam.

My improied hanger con'iprises a vertical portion adapted to lie along the. inside of a chassis beann an upper portion extending outwardly from the. vertical portion so as to overhang the chassis beam, and a lower portion extending inwardly t'rbm the vertical portion so as to support the transu'iission. The vertical portion comprises two sloping legs 1 and 2 connected together by three ribs 3, 4 and The upper portion comprises a flat plate 6 extending outwardly from the two arms 7 and Sextending inwardly from the lower ends of legs 1 and 2 and flaring away from each other, the two arms being connected together by a rib The arms 7 and 8 are provided with a pair of openings l0, 10 near their ends and with a second pair of openings 11, 11 near their bases for attaching th arms to the transmission. Rib 4 and plate (3 are 'irovided I'GSPGCtlVGly with openings 16 and 17 for attaching the'hangcr to the chassis beams. Reinforcing enlargements 12 and 13 are provided at the junctures of the legs and arms, and similar rein-g forcements 14 and 15 are provided between the legs and the overhanging plate 6.

In Fig. 1, I have illustrated the preferred use of my improved hanger. via, for sup porting the change-speed transmission on the chassis beams of an auton-iobile. A

openmgs 17 in plates 6 and thence through alined opening in the channel flanges. Bolts 1.) extend through openings 10 in ribs 4 and thence through alincd openings in the ribs of the channels (7. Spacer blocks 25 of wood or other suitable material are preferably provided between the vertical portions of the hangers and the ribs of the channels. The arms 10. 10 and 11, 11 are secured to the bottom of the transmission casing T by means of bolts 20 20 and 21, 21'.

A cardinal feature of the present inven tion comprises the shape, and arrangement of the arms 7 and 8. By extending the arms inwardly from the legs 1 and 2 a distance substantially as .shown in the drawings, which is substantially equal to the height of the legs 1 and 2, each arm may be secured to the, transmission casing at a plurality of points respectively spaced different distances from the vertical portion of the hanger, whereby the arms may be immovably and permanently secured to the transmission (as ing. However, the arms are not so long as to be unduly subject to breakage. By flar- 1% (nu-Al ing the arms a way from each other the transmission is braced 'against oscillation in a horizontal plane much more substantially. This bracing elihct is n'iaierially supple mentcd and the arms are substantially strengthened by means of ribs 9, particula'rly' by virtue of the fact. that the ribs are disposed substantially in alineinen! with the pairs of openings 20, 20 near the bases of the arms.

I claim:

- l. A hanger for SliPpUl'ilHg the transmission of an anton'mhile or the like comprising a vertical portion adapted to lie, along the side, of a chassiahcaun an upper portion extending laterally fronrlhe vertical portion so as to overhang the chassis l Hill. and a pair at arms extending" laterally from said vertical portion so as to support the transinisaion, said arms extending from the vertical portion a sulricicnt distance to permit the transmission to be attached thereto at a plurality of points spaced ditl'erent diatances from the vertical portion and one of said arms flaring outwardly from the other arm.

2. hanger t'or su liportin a' the transmission otan automobile or the like con'iprising a vertical portion adapted toilie along the side of a chassis lieain, an upper portion extending: lltit 'ally from the vertical portion so as to overhang the chassis beam. :1 pair 01'' arms extending la erally from said vertical portion a": as; to support, thc transmis ion.
